Calibrations involve a method analysis. Daniel's point is that a method of analysis can be flawed if it generates a false positve signal OR if it masks a positive signal. The method analysis should be capable of detecting both a positive (desired) signal and a negative (null, undesired) signal. To test the method analsysis the system should be fed a "dummy" positive signal and "dummy" negative signal. Harry Harry
